<h4>NAME</h4><blockquote>

<P><table  bordercolor=#000000 border=1 align=center><tr valign=top><th align=center><b>Parameters</b>

<p>
This function is used to receive an orderly release indication for
the incoming direction of data transfer.
The argument
<I>fd</I>
identifies the local transport endpoint where the connection exists.
After receipt of this indication, the user may not attempt to
receive more data via 
<i><a href="t_rcv.html">t_rcv()</a></i>
or 
<i><a href="t_rcvv.html">t_rcvv()</a></i>.
Such an attempt will fail with 
<I>t_error</I>
set to [TOUTSTATE].
However, the user may continue to send data over the connection if
<i><a href="t_sndrel.html">t_sndrel()</a></i>
has not been called by the user.
This function is an optional service of the transport provider,
and is only supported if the transport provider returned service
type
T_COTS_ORD
on
<i><a href="t_open.html">t_open()</a></i>
or
<i><a href="t_getinfo.html">t_getinfo()</a></i>.
Any user data that may be associated with the orderly
release indication is discarded when 
<i>t_rcvrel()</i>
is called.
</blockquote><h4>VALID STATES</h4><blockquote>
T_DATAXFER,T_OUTREL
</blockquote><h4>ERRORS</h4><blockquote>
On failure,
<I>t_errno</I>
is set to one of the following:
<dl compact>

<dt>[TBADF]<dd>The specified file descriptor does not refer to a transport endpoint.

<dt>[TLOOK]<dd>An asynchronous event has occurred on this transport endpoint and requires
immediate attention.

<dt>[TNOREL]<dd>No orderly release indication currently exists on the specified
transport endpoint.

<dt>[TNOTSUPPORT]<dd>This function is not supported by the underlying transport
provider.

<dt>[TOUTSTATE]<dd>The communications endpoint referenced by 
<I>fd</I>
is not in one of the states in which a call to this function is valid.

<dt>[TPROTO]<dd>This error indicates that a communication problem has been detected between
XTI and the transport provider for which there is no other suitable XTI
error
<I>(t_errno)</I>.

<dt>[TSYSERR]<dd>A system error has occurred during execution of this function.

</dl>
</blockquote><h4>RETURN VALUE</h4><blockquote>
Upon successful completion, a value of 0 is returned.  Otherwise,
a value of -1 is returned and
<I>t_errno</I>
is set to indicate an error.
